The micro-double-axis gyroscope is a low-precision digital closed-loop dual-axis integrated fiber optic gyroscope. Two mutually perpendicular heads share an SLD light source, which is packaged in an optical circuit and RS422 serial output. The product is small size, light weight and low power consumption.
